A lung scan is a test to look at your child’s lungs using a chemical called a radioactive tracer and a scanner. It uses a radioactive tracer and a scanner to see how well blood flows through the heart and lung blood vessels, and air flows through the lungs.
A lung scan may be done to:
There are 2 types of lung scans. Both may be done on the same day, usually one right after the other.
If your child has a blood clot in his lung, he may need to stay in the hospital for treatment.
The small amount of radioactivity from the tracer is not dangerous. Your child should drink plenty of fluids to help his body get rid of the tracer. It will be completely gone from your child’s body within hours to days.
Ask your healthcare provider:
Make sure you know when you should come back for a checkup. Keep all appointments for provider visits or tests.
Every procedure or treatment has risks. Your child could have an allergic reaction to the tracer. Ask your healthcare provider how this risk applies to your child. Be sure to discuss any other questions or concerns that you may have.
